Agri-environmental auction with synergies Inra
Thoyer, S.; Said, S.; INRA, Institut National de la Recherche Agronomique (FRA); EAAE, European Association of Agricultural Economists (NLD).
Auctions are increasingly used in agri-environmental contracting. However, the issue of synergy effect between agri-environmental measures has been consistently overlooked, both by decision-makers and by the theoretical literature on conservation auction.Based on laboratory experiments, the objective of this paper is to compare the performance of different procurement auction designs (simultaneous, sequential and combinatorial) in the case of multiple heterogeneous units where bidders may potentially want to sell more than one unit and where their supply cost structure displays positive synergies. The comparison is made by using two performance criteria: budget efficiency and allocative efficiency. We also test if performance results are affected by...

Multi-unit auction format design Inra
Hailu, A.; Thoyer, S..
Multi-unit auctions are powerful mechanisms for the allocation of numerous resources and production contracts. However, there is uncertainty about the best auction formats when multi-unit auctions are used because there are multiple equilibria and analytical descriptions of optimum strategies are intractable. Empirical studies are scarce and most experimental studies are restricted to two bidders and two units. This paper constructs an agent-based model of bidders to compare the performance of alternative procurement auction formats under circumstances where bidders submit continuous bid supply functions and learn over time to adjust their bids in order to improve their net incomes. The results provide some confirmation of analytical predictions but also...
